Watch out Adele Nazeem, there’s a seriously talented singer in town, named Idina Menzel, and she can give you a run for your money when it comes to your Oscar-winning tune “Let It Go”—with help from Jimmy Fallon, The Roots and classroom instruments!

In case you missed it, John Travolta introduced Broadway star Idina as “Adele Nazeem” when she took the stage to perform Frozen’s hit song, which went on to win Best Original Song at the 86th Annual Academy Awards.

The 42-year-old was all smiles as she stopped by The Tonight Show and joined Jimmy and his in-house band The Roots for a sing-along sess of “Let It Go” using only classroom instruments (like xylophones, triangles, bongos, etc.) on March 4.
